Quick question, I see a lot of people carbonating with dextrose (corn sugar). Is possible to carb with cane or brown sugar?

American palettes usually enjoy beer carbonated between 2.4-2.7 Volumes of CO2. To style may be more or less and you can visit the BJCp website to find those amounts to style but usually less than 2.2 will taste flat and more than 2.7 will taste excessive to most people
